How does a high level of potassium affect the body?
Potassium plays a role in your nerve impulses, metabolism, and blood pressure. Hyperkalemia occurs when your body can’t filter out extra potassium that it doesn’t need. Extra potassium interferes with your nerve and muscle cells. This can lead to complications in your heart and other areas of your body.
What does too much potassium do to your body?
Too much potassium in your blood can lead to heart conditions, such as an arrhythmia. This condition is also known as an irregular heartbeat. An arrhythmia can result in your heart beating too quickly, too slowly, or not in an even rhythm. Arrhythmias occur because potassium is integral to the electric signal functioning in the myocardium.
What foods will reduce potassium levels?
Foods low in potassium include most refined fats and oils, grains like cornmeal, white rice, and white pasta, cheeses like soft goat cheese, and blueberries, leeks, and napa cabbage.

High blood pressure is a leading risk factor for strokes, so it's no surprise that higher potassium is also associated with a lower stroke incidence. One prospective study that followed more than 43,000 men for eight years found that men who consumed the highest amounts of dietary potassium (a median of 4,300 mg per day) were 38% less likely to have a stroke as those whose median intake was just 2,400 mg per day. However, a similar prospective study that followed more than 85,000 women for 14 years found a more modest association between potassium intake and the risk of strokes. Additional research has mostly upheld these findings, with the strongest evidence to support high dietary potassium seen in people with high blood pressure and in blacks, who are more prone to high blood pressure than whites.

How much potassium is in the body?
The total amount of potassium in the adult body is about 45 millimole (mmol)/kg body weight (about 140 g for a 175 pound adult; 1 mmol = 1 milliequivalent [mEq] or 39.1 mg potassium) [ 3 ]. Most potassium resides intracellularly, and a small amount is in extracellular fluid [ 2-4 ]. The intracellular concentration of potassium is about 30 times higher than the extracellular concentration, and this difference forms a transmembrane electrochemical gradient that is maintained via the sodium-potassium (Na+/K+) ATPase transporter [ 4 ]. In addition to maintaining cellular tonicity, this gradient is required for proper nerve transmission, muscle contraction, and kidney function.
What is the normal potassium level?
Normal serum concentrations of potassium range from about 3.6 to 5.0 mmol/L and are regulated by a variety of mechanisms [ 3, 7 ]. Diarrhea, vomiting, kidney disease, use of certain medications, and other conditions that alter potassium excretion or cause transcellular potassium shifts can cause hypokalemia (serum levels below 3.6 mmol/L) or hyperkalemia (serum levels above 5.0 mmol/L) [ 3, 5, 7, 8 ]. Otherwise, in healthy individuals with normal kidney function, abnormally low or high blood levels of potassium are rare.
What is the cause of hypokalemia?
Severe potassium deficiency can cause hypokalemia, (serum potassium level less than about 3.6 mmol/L) [ 3, 7, 8 ].
